* eval_intern.h (TH_PUSH_TAG): Initialize struct rb_vm_tag::tag with
Qundef rather than 0 which is equal to Qfalse. Since Kernel#throw(obj)
searches a tag with rb_vm_tag::tag == obj, throw(false) can
accidentally find an unrelated tag which is not created by
Kernel#catch. [ruby-core:77229] [Bug #12743]

[Bug #12628]
This patch introduce many changes.
* Introduce concept of "Block Handler (BH)" to represent
passed blocks.
* move rb_control_frame_t::flag to ep[0] (as a special local
variable). This flags represents not only frame type, but also
env flags such as escaped.
* rename `rb_block_t` to `struct rb_block`.
* Make Proc, Binding and RubyVM::Env objects wb-protected.
Check [Bug #12628] for more details.

Note that I don't add those options as default because
it still shows many false-positive (it seems not to consider
longjmp).

`flag' contains several categories of attributes and it makes us
confusion (at least, I had confused).
* rb_method_visibility_t (flags::visi)
* NOEX_UNDEF -> METHOD_VISI_UNDEF = 0
* NOEX_PUBLIC -> METHOD_VISI_PUBLIC = 1
* NOEX_PRIVATE -> METHOD_VISI_PRIVATE = 2
* NOEX_PROTECTED -> METHOD_VISI_PROTECTED = 3
* NOEX_SAFE(flag)) -> safe (flags::safe, 2 bits)
* NOEX_BASIC -> basic (flags::basic, 1 bit)
* NOEX_MODFUNC -> rb_scope_visibility_t in CREF
* NOEX_SUPER -> MISSING_SUPER (enum missing_reason)
* NOEX_VCALL -> MISSING_VCALL (enum missing_reason)
* NOEX_RESPONDS -> BOUND_RESPONDS (macro)
Now, NOEX_NOREDEF is not supported (I'm not sure it is needed).
Background:
I did not know what "NOEX" stands for.
I asked Matz (who made this name) and his answer was "Nothing".
"At first, it meant NO EXport (private), but the original
meaning was gone."
This is why I remove the mysterious word "NOEX" from MRI.
* vm_core.h: introduce `enum missing_reason' to represent
method_missing (NoMethodError) reason.
* eval_intern.h: introduce rb_scope_visibility_t to represent
scope visibility.
It has 3 method visibilities (public/private/protected)
and `module_function`.

everywhere including from within third party C extentions, so
alloca() must be made globally available. [Bug #7307]

dfp (dynamic frame pointer) to ep (environment pointer).
This change make VM `normal' (similar to other interpreters).
Before this commit:
Each frame has two env pointers lfp and dfp. lfp points
local environment which is method/class/toplevel frame.
lfp[0] is block pointer.
dfp is block local frame. dfp[0] points previous (parent)
environment pointer.
lfp == dfp when frame is method/class/toplevel.
You can get lfp from dfp by traversing previous environment
pointers.
After this commit:
Each frame has only `ep' to point respective enviornoment.
If there is parent environment, then ep[0] points parent
envioenment (as dfp). If there are no more environment,
then ep[0] points block pointer (as lfp). We call such ep
as `LEP' (local EP). We add some macros to get LEP and to
detect LEP or not.
In short, we replace dfp and lfp with ep and LEP.
rb_block_t and rb_binding_t member `lfp' and `dfp' are removed
and member `ep' is added.
rename rb_thread_t's member `local_lfp' and `local_svar' to
`root_lep' and `root_svar'.

assume that ep is not LEP.

that ep is LEP.
